Solution Overview

Problem

There is a need for a display apparatus that can detect whether an optical cable plug is attached or detached, and control audio output accordingly, to manage connections with external apparatuses effectively in a user-friendly manner.

Innovation Solution

The display apparatus includes an optical connector and a processor that detects the connection or disconnection of an optical cable plug by receiving electric signals, and controls audio output from an internal speaker to either an external apparatus or back to the internal speaker based on the connection status, displaying appropriate screens to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display apparatus automatically detects optical cable connection status, then audio output management becomes more convenient and user-friendly, but the device complexity increases due to additional detection mechanisms

Engineering Contradiction:
Improveaudio output managementVSAvoiddetection mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The optical connector performs self-detection of cable connection status through built-in detection pins that automatically sense the presence or absence of an optical cable, eliminating the need for manual user input and enabling automatic audio routing decisions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The detection pin provides real-time feedback signals to the processor about the connection status, which then automatically adjusts audio output routing between internal and external speakers based on this feedback, creating a closed-loop control system

Inventive Principle:
Principle #23Feedback

2Loss of information

If the display apparatus provides visual feedback screens for connection status, then user awareness of connection state improves, but the energy consumption increases due to additional display operations

Engineering Contradiction:
Improveconnection status informationVSAvoidenergy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The display shows connection status information selectively and partially - only displaying visual feedback screens when connection status changes occur, rather than continuously monitoring and displaying all possible information, thus reducing unnecessary energy consumption while maintaining user awareness

Inventive Principle:
Principle #16Partial or excessive action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution allows seamless management of audio output between internal and external speakers, enhancing user experience by providing clear visual feedback and efficient audio routing based on plug connections.

Implementation Method 1

The processor may identify whether the optical connector is combined with or is separated from the optical cable depending on whether an electric signal according to contact between the optical connector and the optical cable is received.
